My invention relates to improvements in roller bearings and has for its objectto imrove upon the construction disclosed in my S. Patent No. 1312936 0f August 12, 1919. One object of the invention 1s to provide `1 improved means for securing thel end rings .of the segmental ca e in place so asto prop# erl holdthe cage sgments in assembled relatlon with each other.

y A further object is toprovide a bearing ufactured and marketed, yet .one

be highly eiiicient and reliable.

.With the foregoing in view, the invention whichrwill vresides in the novel subject matter hereinafter described and claimed, the description cutin a common plane with'its axis.

being supplemented by. the accompanying drawings. j

` Figure 1 is a sectional view of the bearing Figures' 2 and 3 .are transverse sectional i views as indicated by lines 2-'.2 'and .3-3 of Fig. 1;

Figure 4! is view.

Figure 5 is a sectional view of the ca e Va disassembled perspective f 'and one form of reinforcing rings in rea 1- ness for assemblage when said rings l are heated to slip over the end rings of the'cage.

. Figure 6 is a view .similar to f5 butv showing a different form of' reinforcing rings. p

Figure 7 is a sectional view showing the reinforcing rings of Fig. 6 spun or pressed into place upon the cage.

.In the drawings above briefly described,

`the numerals 1 and ,2 designate outer and inner bushing members whose adjacent faces are preferably tapered so that-the bushing member 2 is in the form of a cone whose large end is` adapted to abut against some stop shoulder on the shaft upon which it is "mountedr The inner face of the bushing 1 is straight throughout its width but the periphery of the cone 2 is provided with a cirwhich may be easily and inexpensively manmi? y 8D.

'cumferential groove 3 whose edge walls constitute shoulders 4 and 5 to abut the beveled ends 6 and 7 vrespectively of thebearing rollers 8. In the `preferred form of construction, each roller is reduced beyond the shoul- FicE.

der 6 and is provided with a peripheral end flange 9 to abut the smaller end of the cone. The larger end of this cone is provided with an outstanding shoulder 10 spaced from ,the l shoulder 5 for a purpose to appear.

A 'segmental cage is provided for the rollers 8 andas here shown, this cage is construCted-of segmental end rings 11A and 12 A and roller-spacin bars 13 connecting the segments of one o these rings with the cor- -respondin'g's'egments of the other ring. The outer rlpheral edges of these rings are .bevele inwardly towardl each other so that they are nearer to the axis of the cage at thel inner. .sides of said rings, than at'the outer jsides thereof. A pair of one-piece reinforcf'outer sides of the end rings 11 and 12 and -one of these rings is adapted to abut the shoulder 1Q of the conc 2. The reinforcin -rings 14and 1 5 are provided with latera ian'gesI 16 which snugly embrace the end rings. ofthe cage to securetheir segments.

together and' these flanges 16 may either be shrunk around the rings 11 and 12 or they ma -be` spun or pressed into ti ht contact wit the beveled edges thereof. of construction shown in Figs. 1 to 5, the flanges 16 are machined on their inner sides n the form ing rings 14 and 154 are applicableto the to conform t0 the external bevel of the end A rings 11v and 12,. and the rings 14 and 15 are heated so that said flanges 16 are expanded and may easily be slipped over the end rings 11 and 12 to snugly engage the same when cooled. InFig. 6,however, the flanges 16* ofthe rings 14 and 15 aresuch that they be easily slipped overthe segmental rings without heating and may therefore be spun or pressed into Contact with the beveled edges of said end rings. Either method of attaching the rings 14 and 15 may be employed but I prefer to shrink them around the segmental end rings v11. and 12.

The outer sides of the roller-spacing bars 13 are formed with longitudinal channels -17 forming grease pockets. When the bearing is greasecovere'd, these pockets are lled with grease and when the bearing is in use, if its main supply of lubricant is consumed and the bearing heats slightly, the grease will melt and` run from the pockets 17 so 'that injury to the bearing is prevented.

It will be understood that While thel preferred forms of construction have been illustrated, numerous minor changes may be made. For instance, 1t will be seen' thatI the l" rrollers8 need not be of the precise forma- -tion and proportions shown, that the con- ,Jneeting bars for the end rings 'of .the cage I9! -`-L:.- and that the grease pockets 17 may be of any Y niay-be of any desired cross sectional shape,

desired cross section and size.

` I claim:

i ll. A roller bearing comprising a series of qrollers, a segmental cage for said rollers shaving segmental end rings whose outer peripheral edges are beveled inwardly toward each other, and reinforcing rings having peripheral flanges 'surrounding said end rings ripheral flanges shrunk on said endrings and provided with beveled' inner sides snugly contacting with said beveled peripheral ed es of the end rings.-
